Problems of HTR Reservoirs Production Monitoring Using Well Test Methods
Due to the growing share of deposits formed by reservoirs with abnormally low permeability in the assets of oil and gas companies, the geophysical support of the production of such deposits is an urgent task. Conducting and interpreting hydrodynamic studies in reservoirs with abnormally low permeability is a complex task, which requires both, adjusting the methodology for conducting and interpreting studies, and the correct approach to aggregation.
This article examines the problems encountered in well test surveys on hard-to-recover (HTR) reserves, substantiates the prerequisites for the occurrence of key uncertainties, and provides recommendations for well test methods in reservoirs with abnormally low permeability.
Geological Activity of Shale Diapir in Bao Vang Field, Block 111-113, Centre of Song Hong Basin
Diapirs are very common in the center of the Shonghong Basin in the north of the continental shelf of the Socialist Republic of Vietnam. They are formed as a result of the release of high pressure in the Oligocene, Miocene layers. Exploration results show that gas discoveries in the Bao Wang field and adjacent fields are closely related to shale diapirs. This article is devoted to the results of diapirs interpretation, their activity based on the latest 2D, 3D seismic data from the Bao Wang field, blocks 111-113. The article also discusses and evaluates the origin, formation mechanism and role of diapir activity in relation to oil and gas accumulations
Justification of Productive Interval Penetration Path for Horizontal Drilling
This paper discusses practical examples of justifying the horizontal wellbore path of a gas-bearing formation. Various possible paths have been proposed, taking into account the geological characteristics of the field and numerous factors affecting the productivity of horizontal wells, with respect for synchronous decrease in reservoir pressure in the productive layers
Analysis of influence of properties of real and ideal gases on thermal conductivity of oil and gas-liquid mixture
One of the problems that throughout the history of commercial oil production significantly has been complicating wells operating conditions is paraffin deposits. There are a number of factors contributing to the formation of paraffin deposits, with changes in well temperature and pressure conditions being most significant, in particular, a decrease in the temperature of the fluid during production. Today, fluid temperature distribution along the depth is rarely measured in wells. Therefore, for most wells, it is necessary to build thermograms using the corresponding calculated dependencies. To implement the required calculation algorithm, a basic set of initial data is required. Due to the fact that the fluid is a mixture of oil, water and gas, many of the necessary parameters must be calculated specifically for the mixture, for example, density, heat capacity, thermal conductivity. The first two are calculated according to the mass additivity rule, whereas for thermal conductivity there are several calculation methods applicable to a particular case.
The article presents a methodology for calculating the coefficient of maximum thermal conductivity of a fluid. A comparative analysis of the effect of the properties of real and ideal gases on the calculated coefficient of maximum thermal conductivity of the fluid is also carried out.
Refined estimation of vibration of pipelines transporting oil and gas
The article provides a conclusion of theoretical dependencies of the updated estimation of the vibration state of oil and gas pipelines. They are based on the turns of pipelines during vibration. When deriving the equations, such an important factor as “chain forces” is taken into account. The natural frequencies of vibration motion are estimated taking into account the inertia of the rotation of the cross sections of the pipe and the condition for the occurrence of resonance
On the mechanism of heat and mass transfer of moisture under thermal influence on frozen soils during the construction and operation of oil and gas pipelines
Issues of construction, ensuring reliable and safe operation of oil and gas pipelines at the facilities of the energy complex of the Russian Federation are a priority. From this point of view, the results of research on the working processes of soil development with thermomechanical equipment of a new generation are considered. Based on the results of theoretical and experimental studies, the mechanism of heat and mass transfer of a vapor-gas mixture from a coolant in a pit in frozen soils is justified. Recommendations are given for methodological support of working processes and technology of soil development with thermomechanical equipment during construction and operation of oil and gas pipelines in frozen ground conditions
Automation of design and technological preparation of gear production by copying method
The article discusses the problems of automation of technological preparation for the production of spur involute gears using the copy method. The performance capabilities of the software module developed by the authors are described. These allow to reduce the labour effort of design, technological and economic calculations. The software application has been tested on milling and EDM equipment, with the help of contouring, gears with an exact involute profile have been obtained
The article presents the results of studies on catalytic pyrolysis of the gasoline fraction using the mineral sillimanite as a high-temperature aluminum catalyst to effectively increase the output of olefins. The process of pyrolysis on such a catalyst is based on the high temperature resistance of sillimanite (used for the production of fire retardants in the steel industry and in the production of cera-mics) and the presence of more than 50 % of active aluminium atoms concen-
trated in tetrahedrons. Based on the results of practical studies for the new high-temperature sillimanite catalyst, the equation of kinetics of the pyrolysis process of the gasoline fraction has been developed, and constants on the theory of transitional state have been determined. Studies at the pyrolysis laboratory have shown that sillimanite catalyst is a significant activator of the process
Gel-generation of systems based on aluminum polyoxychloride under various physicochemical conditions
Тhe influence of terrigenous rocks mineralogical composition and water chemical composition on gel-generation time of systems based on aluminum polyoxychlorides was studied. It was shown that with an increase in rocks clay and carbonate content, the gel-generation time decreases linearly for the VIS-1 system and exponentially for the SiXell system. It was established that with an increase in water mineralization, the time of sedimentation decreases, showing a larger decrease for sodium hydrogen carbonate waters due to their greater alkalinity. It was determined that these processes are associated with a change in the pH of solutions of gel-generation systems in the presence of alkaline and alkaline-earth metal ions contained in water and rock
Requirements for continuous monitoring systems of oil-contaminated areas
As a result of the development of oil production and refining industries, the risk of emergency oil spills increases. The complex chemical composition of oil and petroleum products leads to a number of environmental problems related to changes in the biological and microbiological properties of the soil cover, as well as to extensive damage to plants and animals. The process of natural rehabilitation of oil-contaminated soils is long and requires new technologies for continuous monitoring. The analysis of the collected data allows to correct and predict the progress of restoration of disturbed territories under the influence of many factors using the construction of a multidimensional trajectory. It is first proposed to use process-analytical technology (PAT) to control the restoration of contaminated areas
